I travel by train or car more often than not - only one international flight so far for business.
I don't stay at the same hotel chain or fly with the same airline enough to really benefit from reward programmes. That said when travelling to India this year with work I managed to collect enough miles for a free night which I used this year... saved me £105!
I am obsessed with packing / travelling light / new bags etc
My wife travels with work more than me (including domestics flights) and can travel lighter than me - and she doesn't even try as it seems to come naturally.
I turn up way too early to the train station / airport. In the case of the airport I can't 'rest' until I have passed security and the 'right' side of the airport.
